[0003] Existing biomass-burning gasifiers produce a large amount of flue gas during use, and these flue gases contain a certain amount of particulate matter after biomass combustion, and these flue gases will affect the surrounding workers during the emission process. In order to address the above problems and defects, there is an urgent need for a biomass-burning gasifier that can efficiently exhaust smoke. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a biomass burning gasification furnace with efficient smoke exhaust to solve the problem that the existing biomass burning gasification furnace will generate a large amount of smoke during use, and these smokes will contain certain particulate matter after biomass combustion, and these smokes will affect the surrounding workers during the emission process.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] The top of the filter press is fixed with a top cover, and the bottom cover is fixed with a top cover, and the filter press has a filter press at its top, and a filter press at its bottom.

[0007] A square groove is provided on the top of the gasification furnace body, and a hanging ring is rotatably connected to the inner wall of the square groove.

[0008] The outer wall of the filter screen is provided with a connecting groove, and the inner wall of the connecting groove is fixedly equipped with a cross bar.

[0009] The cross-sectional shape of the positioning groove is an isosceles trapezoid.

[0010] The combustion aid is a normal pressure premixing burner.

[0011] There are two fans, and the two fans are symmetrically distributed on both sides of the connecting block.

[0012] Compared with the prior art, the present invention has at least the following beneficial effects:

[0013] 1. In the above scheme, when the gasifier body is in use, the fan provides suction to move the flue gas generated during the operation of the gasifier body toward the fan. At this time, the filter filters the flue gas and then discharges the filtered flue gas out of the gasifier body. After the operation is completed, the shaft is rotated by turning the knob, and the connecting rope is moved by the rotation of the shaft, thereby pulling the card block to the depth of the groove. At this time, the filter can be taken out. After the filter is cleaned, the above steps are repeated and the filter is inserted into the connecting pipe to ensure the normal use of the device, which is beneficial to improving the smoke exhaust effect of the device and the filtering effect of the flue gas, and ensuring the working conditions of the surrounding staff.
